Spinal Compressor and Distractor
Abstract
A combined apparatus for compression and distraction of a first physical component having a first bone screw and a second physical component having a second bone screw, said apparatus comprising a connected rod fixedly connected to one of the first and second bone screw heads and slidably connected to the other of the first and second bone screw heads, a rod holder, and an adjusting member comprising an adjusting means and a turning means, such that when the adjusting member is turned by use of the turning means, the adjusting means forces an increase in distance between the rod holder and adjacent bone screw head, resulting in compression or distraction as desired of the physical components.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:

2 . The apparatus of claim 1 wherein said adjusting means comprises at least one of a cam and a blade.
3 . The apparatus of claim 1 wherein said turning means comprises a hex profile.
4 . The apparatus of claim 1 wherein said rod holder is detachably attached to said connecting rod.
5 . A combined tool apparatus for compression or distraction of a first physical component having a first bone screw and a second physical component having a second bone screw, said apparatus comprising:
a. a first bone screw and a second bone screw, each of said first bone screw and said second bone screw comprising a screw, a collar, and a screw head; b. a connecting rod mounted fixedly to said at least one of said first bone screw and said second bone screw and mounted slidably to at least one of said first bone screw and said second bone screw; c. a rod holder attached to said connecting rod adjacent to said first bone screw at a location between said first bone screw and said second bone screw; d. an adjusting member comprising a turning means and an adjusting means, said adjusting member disposed over said first bone screw head, wherein the adjusting means of said adjusting member will cause an increase in the distance between said first bone screw head and said rod holder when said adjusting member is turned.
6 . The apparatus of claim 5 wherein said adjusting means comprises at least one of a cam and a blade.
7 . The apparatus of claim 5 wherein said turning means comprises a hex profile.
8 . The apparatus of claim 5 wherein said rod holder is detachably attached to said connecting rod.
9 . A combined tool apparatus for compression or distraction of a first physical component having a first bone screw and a second physical component having a second bone screw, said apparatus comprising:
a. a first bone screw and a second bone screw, each of said first bone screw and said second bone screw comprising a screw, a collar, and a screw head; b. a connecting rod mounted fixedly to said at least one of said first bone screw and said second bone screw and mounted slidably to at least one of said first bone screw and said second bone screw; c. a rod holder attached to said connecting rod adjacent to said first bone screw at a location between said first bone screw and said second bone screw; d. an adjusting member comprising a turning means and an adjusting means, said adjusting member disposed over said rod holder, wherein the adjusting means of said adjusting member will cause an increase in the distance between the rod holder and said first bone screw head when said adjusting member is turned.
10 . The apparatus of claim 9 wherein said adjusting means comprises at least one of a cam and a blade.
11 . The apparatus of claim 9 wherein said turning means comprises a hex profile.
12 . The apparatus of claim 9 wherein said rod holder is detachably attached to said connecting rod.
13 . A combined tool apparatus for compression or distraction of a first physical component having a first bone screw and a second physical component having a second bone screw, said apparatus comprising:
a. a first bone screw and a second bone screw, each of said first bone screw and said second bone screw comprising a screw, a collar, and a screw head; b. a connecting rod mounted fixedly to said at least one of said first bone screw and said second bone screw and mounted slidably to at least one of said first bone screw and said second bone screw; c. a rod holder, wherein said rod holder further comprises an adjusting member and is attached to said connecting rod adjacent to said first bone screw at a location between said first bone screw and said second bone screw, wherein the adjusting member comprises an adjusting means and said adjusting means will cause an increase in the distance between said rod holder and said first bone screw head when said adjusting member is turned.
14 . The apparatus of claim 13 wherein said adjusting means comprises at least one of a cam and a blade.
15 . The apparatus of claim 13 wherein said turning means comprises a hex profile.
16 . A combined tool apparatus for compression or distraction of a first physical component having a first bone screw and a second physical component having a second bone screw, said apparatus comprising:
a. a first bone screw and a second bone screw, each of said first bone screw and said second bone screw comprising a screw, a collar, and a screw head; b. a connecting rod mounted fixedly to said at least one of said first bone screw and said second bone screw and mounted slidably to at least one of said first bone screw and said second bone screw; c. a rod holder attached to said connecting rod adjacent to said first bone screw, but not at a location between said first bone screw and said second bone screw; d. an adjusting member comprising a turning means and an adjusting means, said adjusting member disposed over said rod holder, wherein the adjusting means of said adjusting member will cause an increase in the distance between the rod holder and an adjacent bone screw head when said adjusting member is turned.
17 . The apparatus of claim 16 wherein said adjusting means comprises at least one of a cam and a blade.
18 . The apparatus of claim 16 wherein said turning means comprises a hex profile.
19 . The apparatus of claim 16 wherein said rod holder is detachably attached to said connecting rod.
20 . A combined tool apparatus for compression or distraction of a first physical component having a first bone screw and a second physical component having a second bone screw, said apparatus comprising:
a. a first bone screw and a second bone screw, each of said first bone screw and said second bone screw comprising a screw, a collar, and a screw head; b. a connecting rod mounted fixedly to said at least one of said first bone screw and said second bone screw and mounted slidably to at least one of said first bone screw and said second bone screw; c. a rod holder, wherein said rod holder further comprises an adjusting member and is attached to said connecting rod adjacent to said first bone screw, but not at a location between said first bone screw and said second bone screw, wherein the said adjusting member comprises an adjusting means and said adjusting means causes an increase in the distance between said rod holder and said first bone screw head when said rod holder is turned.
